ABSTRACT:
This invention relates to a process for producing a printing-ink stock. According to the invention, a solid and oxidation-sensitive thermoplastic resin binder and a pigment are supplied to an extruder and combined therein to form a pigment dispersion. In an end zone of the extruder and/or shortly after discharge from the extruder, a liquid diluent is added to the pigment dispersion to produce a more or less viscous, liquid, stabilized product. The invention also relates to a printing ink produced from the product so obtained.
